Chinese Lanterns in your greenhouse

For a wonderful display in your greenhouse or conservatory all winter through you just cannot beat Chinese Lanterns. These are long stems festooned with numerous orange ‘flowers’ and so called as they so closely resemble brilliantly coloured paper decorations. Also known as Bladder Cherries Physalis alkekengi really are most distinctive and have been grown since […]

Spider lilies and Peruvian Daffodils

You need a heated greenhouse or conservatory where the temperature never drops below 20°C/70°F to safely grow these rare bulbous plants known in Latin as Hymenocallis. Very closely related to Amaryllis (note the similar strap like leaves) these are amongst the most beautiful of flowers carrying a heavy vanilla perfume to add to their pristine […]

Apios, hopniss, a forgotten gem

Apios is one of those forgotten greenhouse gems seldom come across nowadays. It was once very popular in late Victorian times for the violet scent from the small racemes of purplish flowers. However after the First World War the shortage of labour and its slight tenderness made this plant unattractive. Indeed in the UK it […]

Long flowering guaranteed (Polygala)

Polygala x Dalmaisiana is a superb choice for conservatories and cool greenhouses with beautiful purple pea like blooms throughout much of the year. These decorative flowers are produced almost continuously along the ends of lax stems of attractive grey green evergreen foliage. Not so much an impressive centre piece perhaps but excellent as the supporting […]

There’s no point to this yucca

An extremely architectural glass-house and house-plant is Yucca elephantipes, the Spineless Yucca or Palm-lily. This is a closely related species to Adam’s Needle (Y. filamentosa), the hardy Yucca of the open garden. Don’t worry the Palm-lily does not have such cruelly pointed leaves. There is still a vestigial point to each but nowhere near as […]

What’s the most nutritional glasshouse crop?

This depends on so many different factors. We might consider concentration, range or sheer quantity of vitamins produced. Or minerals, antioxidants, antho-cyanins each contains and so on. Any contender will be lesser value if the crop comes all at once and has difficult storage or processing, ideally it’s continuous year round. And of course it […]


Snake or perhaps it should be Witch plant

More a house than a glasshouse plant the Snake plant, Sanseviera trifasciata, is actually a very useful specimen in either place. Many plants are described as bomb-proof, the Snake plant is as close as you can get. Drought and shade seem to leave it untouched, cold is no problem though a real freeze will be. […]

Yacon, llamon, cochet, aricoma, jiquima, poire de terre

You need a generous greenhouse to freely accommodate Yacon as this can easily grow two, three or more metres high. Fortunately it can also be cut back down so you can squeeze one into a smaller space. But be warned this has expansionist tendencies and in small houses is best confined in a large tub […]
